CAUTIONS
Clearance of 12" from any combustible surface must be maintained.
Do Not connect the inputs of the Impulse 115P to the output of a power amplifier. The inputs are meant to
be driven from a line level signal.
Do Not remove the protective grill.
Do Not use the left input jack group or right input jack group as mixers by trying to run more than one
signal source at a time into either channel group. The left input jack group or right input jack group (5) are
hard-wired together to allow use of any of the connector types as an input and to allow a further send or
daisy-chaining of the input signal to some other audio device (such as another Impulse 115P). Attempting
to run two different signals into the Impulse 115P left input jack group or right input group could damage
the outputs of the source units. Use a mixer to combine two or more signals into a single channel of the
Impulse 115P inputs.
Warning: The Impulse 115P is extremely efficient and powerful. This sound system can permanently
damage hearing. Use extreme care when setting the overall maximum loudness.
The apparent sound level of the Impulse 115P can be deceiving. Due to the clear‚ clean sound output of
the Impulse 115P and the lack of distortion or obvious distress‚ the sound level seems much lower than it
actually is. This system is capable of SPLs in excess of 128 dB at 1M from the speaker!

The built-in pole adapter allows for the use of the Impulse 115P as a base for a variety of passively
crossed-over 2-way speakers or powered speaker systems. These speakers should not exceed 29" in
height or 70 lbs. in weight.
The accessory pole that it is designed to use is Peavey part #00326540. The pole used is 36 3/16" long
and has a nominal diameter of 1 3/8". The stand pole must be fully seated all the way down into the
Impulse 115P pole tunnel before any speaker can be mounted on top of the pole.

The Impulse 115P is shipped with an 8 ft. IEC connection AC power cord. If you are using an extension cord
or power strip with this powered speaker‚ make sure it is of good quality and of a sufficient current
capacity to maintain safety and maximize the power output capability of the Impulse 115P. Do not connect
any other device to the same extension cord that the Impulse 115P is connected to.

There are a variety of ways to get a signal to the Impulse 115P. The balanced line-level input(s) allow the
use of a 1/4" phone plug: either a standard single-ended TS (tip/sleeve) plug or a balanced RTS
(ring/tip/sleeve) type plug. Or‚ you may use a XLR plug. Do not connect cables to the jacks while the units
are on and the volume is turned up.
While the standard‚ single-ended 1/4" phone plug will work and the balanced input circuitry will provide
some interference rejection‚ a balanced cable using either the TRS 1/4" plug or the XLR plug will provide
superior performance. Plugging into the RCA jacks or plugging a mono‚ 1/4" plug into the combo jack will
cause the thru jack to operate in unbalanced mode. Sometimes‚ with difficult interference problems‚ it will
be helpful to lift the shield ground on a balanced cable at the Impulse 115P end only. This can be
accomplished via the convenient ground lift switch (10a) found underneath the input jack group. Check
any input changes carefully. Always turn the volume controls down before plugging and unplugging cables
or switching the ground lift switches.
Use of high-quality‚ premium cables is recommended for the Impulse 115P. These cables typically have
better shielding and materials and will provide greater long-term reliability. It is also a good idea to leave
some slack at each end of your cable connection and tape the cables down or run them under a cable
guard to avoid accidents.
